- [Narrator] For six months of the year,

crystal blue lagoons appear in what would otherwise

look like your average desert,

making Lençóis Maranhenses

one of Brazil's most mysterious destinations.

Lençóis Maranhenses is a national park located in Brazil.

From January to June, the area

becomes inundated with rain storms.

The rain water collects between the sand dunes,

creating thousands of clear water lagoons.

Some of these pools reach over 300 feet in length

and can be over 10 feet deep.

With water temperatures as high as 87 degrees,

visitors come from far and wide

to experience the pristine conditions.

But arriving at these pools is no easy feat,

and renting a four-wheeler is a must.

The ride is rough, as you need to cross tight spaces

and navigate through rivers and puddles.

Lençóis Maranhenses visitors must enjoy these pools

while they can, because come dry season

this spectacular landscape vanishes

and returns to its desert form once again.
